Why teams connect Elasticsearch and Rillet

Work with Rillet's financial data straight from Elasticsearch: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Account, Customer, Vendor, Invoice from Rillet into Data streams, Ingest pipelines, Index templates, Indices in Elasticsearch and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Elasticsearch, and rows your code writes or updates flow back into Rillet with validation, so the finance system stays the system of record.

Common use cases

  • Keep customers and invoices aligned between Rillet and a CRM so finance and sales work from the same account records.
  • Mirror journal entries and contract revenue data into a warehouse for board and ARR reporting.
  • Mirror support tickets into an index used for full-text search and agent-assist tooling.
  • Feed enriched customer records into an index used for vector or hybrid search in AI applications.

React to financial events

Changes in Rillet appear in Elasticsearch as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Rillet live in Elasticsearch as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

Build dashboards and back-office tools directly on Elasticsearch; Stacksync handles the API calls, rate limits, and retries against Rillet.

What you can sync between Elasticsearch and Rillet

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Elasticsearch objects Rillet objects
Index mappings Field type definitions that determine how synced fields are indexed and queried. Customer Synced with incremental and full sync per the Stacksync docs.
Aliases Stable read/write names that let a sync cut over between index versions without downtime. Vendor Synced with incremental and full sync per the Stacksync docs.
Data streams Append-only targets for time-series or event data pushed from source systems. Invoice Synced with incremental and full sync per the Stacksync docs.
Ingest pipelines Server-side transforms applied to documents as a sync writes them. Credit Memo Synced with incremental and full sync per the Stacksync docs.
Index templates Reusable settings and mappings applied automatically to new indices a sync creates. Bill Synced with incremental and full sync per the Stacksync docs.
Indices Target containers for synced records; each holds a table-like collection of JSON documents. Journal Entry Synced with incremental and full sync per the Stacksync docs.

How the Elasticsearch and Rillet connectors work

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities
read · write
Rate limits
No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity

Rillet

Integration surface
REST API (OpenAPI-specified, with production and sandbox environments)
Authentication
API key generated in Rillet (Organization Setting -> API Access); uncheck Read Only for bidirectional sync, check Read Only for one-way sync
Change detection
Near real-time updates via change tracking; incremental sync per object, with delete detection (some objects checked every 1h or 4h)
Capabilities
read · write · CDC · webhooks
Rate limits
Subject to the platform's API rate limits.
